Our PLU20 series four-point contact ball slewing bearings are designed to meet the needs of light to medium load applications. While ensuring high precision, they have a compact structure and flexible rotation performance, making them an ideal choice for various construction machinery and automation equipment.
Four-point contact ball slewing bearing is a special bearing that can simultaneously withstand axial force, radial force and overturning moment. Its unique raceway design enables a single ball to achieve four points of contact on the inner and outer raceways, thus ensuring efficient and stable load-bearing performance.
